It's already been said but everytime a Haimer is fixed into a collet it needs to be adjusted or you can expect .001"-.002" runout. Also the Haimer's large dial needle needs to be adjusted to 0. None of my Haimer probes(I have two) dials have come as zeroed as they can be.
Please note that a run out in the collet is going to affect your reading with the 3D Touch probe, where as the wiggler is going to compensate for that by always running true to the spindle regardless of run out. Watch this for an explanation: th-cam.com/video/bga7y4infIo/w-d-xo.html
check out 1:40 of the video, by adjusting the heimer the ball will run true to the center. Of course that only holds true if you use it on the same machine and don't remove it from the tool holder, once you change anything in the setup you have to adjust the heimer again. At that point the only tolerance you will face is the repeatability of your toolholder.
Actually to get the best out of these Haimer 3D units they need to be zeroed to the spindle C/L and then left in the tool shank it was zeroed with. For an R8 spindle I just used a common 3/4" end mill holder. This tool is the only use I've ever found for that internal set screw R8 tapers have since the tool is indexed to the same position each time. For other spindle tapers I think I'd add an index mark to the spindles OD and on the tool shank where it can be easily seen so the tool is correctly indexed to the spindle each time it's used. A slightly worn taper might make that indexing a lot more important than for a brand new machine. Yes dropping one would make for a very bad day. I don't believe there's anyone qualified to repair them other that the manufacturer.
Only thing that annoys me with these 3D testers is the z obviously needs a height offset of the device itself taking into account. I have one to use on our mazaks and it means i have to have a tool number permanently assigned to the tester, so that when I use it to set Z. it calls up the right height offset. Its a pain caus the tester is not in the tool changer, so I have to empty the spindle, put the thing in then use MDI to tell the machine its got the tester in the spindle, all so it loads the right offset. It works very well, but its a big of a faff to get it in the machine and ready to work each time. X/Y is not a problem, you can just take any tool out and put the tester in (with mazak smooth, you can only use a machine position to base an offset from if you have a measured tool in the spindle). Its not as good as a proper probe, but it works. Used to use a wiggler, but this is easier.
+Nacer Ziani Thanks Nacer! We're going to look at the effect of climb/conventional milling next week so stay tuned! Are you involved in machining or do you just find this kind of thing interesting?

The Haimer 3D Sensor is 28 times more expensive than the Wiggler, NOT 3 times, as you stated at the beginning of this video!!
Theres something called a figure of speech something that isnt quite true but you get the meaning
You still can't beat a cigarette paper and rotating cutter touch off. Costs only a few cents.

how you know haimer acurate? what if they calibrate it wrong. can it be calibrate? wigler is allready pass centre line when it jumps
+Jari Sipilainen all good points. Any decent workshop calibrates and maintains their kit.

Thanks for the vid

+FutureFab CNC & 3D Printing Thanks a lot , I 'll be waiting :)
+Nacer Ziani If you don't mind , I suggest more vids about feed and speed (not how to calculate) I mean feed and speed deo to your experience .
